SCALLOPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 486,408, dated November 15, 1892.

Application filed April 15, 1892- Serial No. 429,242. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY LOEWER, of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Scalloping-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in scalloping-machines, and has for its object the production of a simple, practical, and efficient attachment which can be readily adjusted to the required size of the scallop or the conformation of the pattern or the article to be scalloped; and to this end it consists,

essentially, in a frame having radial guideways, a series of bars or arms adjustably mounted in said guideways and formed with serrations along corresponding edges, a movable plate for engaging the serrations of the bars or arms, and heads hinged to the outer extremities of the arms or bars.

The invention furthermore consists in a flexible connection between the heads, a pattern-holder adj ustably supported between adjacent heads and arranged with its lower end adapted to project beneath the plane of the lower faces of the heads and beyond the plane of the outer faces thereof, and in the detail construction and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is atop plan view of my invention, illustrating the general construction and arrangement of the parts. Fig. 2 is a similar top plan view, the upper plate for securing the bars or arms imposition being shown as removed and the parts as adjusted to conform to a pattern shown as operatively engaged by the pattern-supports. Fig. 3 is a transverse vertical sectional view taken on line 3 3, Fig. 1. Fig. 4 is a similar vertical sectional view taken on line 4 4, Fig. 2, illustrating the opposite side of the attachment to that shown at Fig. 3. Fig. 5 is a longitudinal vertical sectional view taken on line 5 5, Fig. 1. Figs. 6 and 7 are respectively vertical and horizontal sections of one of the detached heads secured to the adjustable bars or arms, the adjacent end of one of the bars being shown by dotted lines and the pattern-support being shown in section at Fig. 7. Fig. 8 is an elevation of the detached end of one of the bars or arms, and Fig. 9 is an isometric perspective of one of the detached pattern-supports.

It is well known that there has been a demand for a cheap and practical device for facilitating the formation of scallops of economical manufacture and capable of ready adjustment to the required size of the scallops and the conformation of the pattern or the article to be scalloped, and by my invention I produce a device possessing these qualifications, as will be readily apparent upon reference to the following description and the accompanying drawings.

The frame A of my attachment is of desirable form, size, and construction, and, as here shown, consists of the base-plate A, formed with radial guides or upright slots at, and the top plate A provided with an upwardly-extending hub a and a spindle or cylindrical spur a rising from the hub and adapted to be attached to a support A not necessary to specifically illustrate or describe, it being understood that it is preferably reciprocal for moving the frame toward and away from the articles to be'scalloped.

At the ends of the base-plate A are upwardly-extending cylindrical arms a passed through openings a in the corresponding ends of the top plate A and eccentrically pivoted to the upper projecting ends of these arms is a cross-bar B. At the inner side of the openings a are upwardly-extending ears a on the top plate A which are each formed with a top bearing -face a", and midway between these cars is a central ear (1, having an upper bearing-face a The cross-bar B is formed with a crank-arm b for rocking the same on its eccentric trunnions b, journaled in the arms 01, a and as the crank-arm is forced downwardly into its position shown at Fig. 4 the cross-bar B bears against the faces at a and a and forces the top plate A of the frame firmly against the lower plate A. To separate the plates A A the crank-arm b is forced upwardly, rocking the cross-bar B, and the lower plate A by force of gravity feeds downwardly, drawing the crossbarBagainst the faces a a a upon the top plate, which, as previously stated, is mounted on a support A C C represent bars or arms having one end 0 o adjustably movable in the guides a a of the frame base-plate A and their corresponding upper edges adapted to project slightly above the top face of the base-plate A and formed with serrations 0', adapted to be engaged by the under face of the top frameplate A which is preferably provide-l with a yielding face-plate A of suitable material for firmly holding said bars in their adjusted position.

D D are heads provided upon the outer ends o c of the bars or arms 0 and formed with inwardly-extending grooves d in their outer faces, having curved sides d d extending toward the adjacent sides d 01 of the heads. The outer faces of these heads D D form, essentially, the outer face of the bars or arms C 0, even though I preferably hinge said heads to the bars for rendering my invention particularly practical and eificient. The opposite sides (1 d of the preferable form of head D taper slightlyoutward,and the rear side d of the head is convexly-curved and is provided with a socket D, having its lower extremity D of less diameter than its upper extremity, and with an upright slot D opening into the upper end of the socket. The outer end of each of the bars or arms is formed with an enlargement O,registered with the upper portion of the socket D, an annular shoulder 0 adapted to rest upon the shoulder D of the socket D, and a depending nipple C adapted to enter the lower portion D of the socket D. It will thus be seen that the heads D D are removable from their respective supporting bars or arms and are movably mounted thereon, so as to permit of anindependent hinge movement of each head D upon its respective supporting-arm, thereby greatly aiding the formation of scallops of corresponding contour. These heads D D are connected together by a suitable connection E, consisting, preferably, of a spring-wire passed through openings D in the upper por tion of the heads directly above the upper face a of the bars C, whereby the spring serves, also, to connect saidheads to their respective arms.

The bars 0 are independently adjusted outwardly to the desired degree, and the heads D have an independent hinge movement upon said bars, which is restrained or governed by the flexible connection E, so that the adjacent sides of the heads are comparatively close together and substantially equidistant, and the adjacent sides d d of the slots din the adjacent heads form segments of a series of broken scallops. \V hen the bars are adjusted as described, the top plate A is forcibly clamped against the inner ends thereof for preventing their disarrangement.

In use the operator adjusts the bars, as described, to the required number of scallops and the conformation of the pattern or the article to be scalloped, clamps the barsin their adjusted position, brings the attachment into contact with the articles to be scalloped, which are arranged beneath the front ends of the bars 0, and guides his cutting-tool along the curved outer faces of the heads D.

In order to facilitate the adjustment of my attachment to a pattern, I provide the same with a series of pattern-holders F. (Best seen at Figs. 1, 2, 4, and 9.) As here illustrated, these holders consist of metallic plates, which may be readily stamped from sheet metal at a minimum expense and are adj ustably mount ed between the adjacent sides of the heads D.

The lower endfof the pattern F is formed with a slot f, having a lower Sl10llltl6lf arranged normally beneath the lower faces (1" of the heads D for supporting a pattern G, Fig. 2, anda forward shoulder f normally in advance of the extreme frontsurface of the heads D, so as to provide for the ready re moval of the pattern from beneath the heads when desired to use the attachment and the presence of sufficient material in advance of the heads to permit of the required trimming along the scalloped edge of the article to he scalloped. The central portion F of the pattern-holder is curved rearwardly and upwardly and is formed withacorrespondinglycurved slot f, with which is registered ascrew f secured to the adjacent face of the head D for supporting said pattern, as seen at Fig. 7. The opposite face of the adjacent head is formed with a cutout d for receiving the head of said screw when desired to closely approximate the adjacent sides of the heads. The upper extremity of the pattern-holder is formed with an upright slot F for receiving the wire or flexible connection E and causing the lower end f of said pattern-holder to rock inwardly as my improved attachment is forced toward the article to be scalloped and the pattern-holder raised upwardly by encounter with said object.

It will thus be understood that when my improved attachment is in operative contact with the article to be scalloped the patternholders are, with the exception of their upper extremities, entirely concealed between the adjacent heads, and that since their lower ends are readily forced upwardly and rocked inwardly they do not retard the formation of the scallops.

The operation of my invention will be readily understood upon reference to the foregoing description and the accompanying drawings. It will be particularly noted that the frame is simple, the bars or arms readily adjustable, the heads readily attached to the bars and capable of independent movement thereon, the pattern-holders particularly effective for holding the pattern and of such construction as to be readily forced out of their operative position when desired to form the scallops, and that all of the parts are economically constructed, readily assembled, and practical and efficient in operation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
